Make sure that LaTeX sees a \par (e.g., a blank line)
at the end of each item, *before* the next \item .

Otherwise TeX does not know that the paragraph has actually finished
yet.
This could mean that the next \label (when at the start of the item,
as you had it previously) gets processed before the line-breaking
for the previous contents have been established.

The \par ensures that the paragraph (i.e., the item content) has
finished,
so makes for cleaner processing.

Hope this helps,
